UIMA-DUCC Codebase Intellectual Property (IP) Clearance Status


Distributed UIMA Cluster Computing (DUCC) is a cluster management system providing tooling, management, and scheduling facilities to automate the scale-out of applications using the UIMA framework.

Core UIMA provides a generalized framework for applications that process unstructured information such as human language, but does not provide a scale-out mechanism. UIMA-AS provides a scale-out mechanism to distribute UIMA pipelines over a cluster of computing resources, but does not provide job or cluster management of the resources. DUCC completes the set by providing job support, cluster management, and life-cycle automation for the scale-out of UIMA applications, using UIMA-AS, on large computing clusters

The contribution includes components that use Apache ActiveMQ and Apache Camel as a messaging infrastructure. It also includes Jetty to display DUCC's cluster information in web browsers, as well as enabling cluster control.

The contributed code is in the "sandbox" area of the UIMA SVN: , where it is being cleaned up and otherwise worked on. The original donation is in a zip file attached to a JIRA issue:

The donation codebase is a set of new modules and documentation and does not contain patches for other components.
